' IMPROVEMENT m SPARK-ARRESTERS.

Speciiicatiouforming part of Letters Patent No. 176,865, dated May 2, 1876; application filed February 5, 1876. v

To all whom it may concern Be it known that I, WALDO H. JORDAN,

of the city, county, and State of New York,

cation thereof, which will enable any person 1 skilled in the art to make anduse the same.

This invention is intended to effect the ar:

rest of sparks, cinders, unburned fuel, and other solids that rise from chimneys with the gaseous products of combustion. The inven- 'tion is especially applicable to the chimneys.

of locomotives, butit may be used in connection with chimneys of everydescription.

1 My inventionconsists of an uninclosed annular cap or shell deflector, of conical exterior form, having a diameter sufficient to cover both the mouth of the chimney and the mouth of the cinder-receptacle which is made around the chimney, the said deflector having its vinterior provided with a parabolic deflecting surface that begins at the center of the shell, curves upward and outward, then downward to the outer edge of the shell. This shell or cap is uninclosed, and is placed above the mouth of the chimney, with the center of said deflecting surface over the center of the chim-.

ney, so that when the products of combustion rise they impinge upon said deflecting-surface, which serves to turn and reverse'the solid particles or cinders, sending them down into an annular receptacle n which surrounds the chimney, while the smoke and gases pass laterally from the interior of the shell to the atmosphere. The cap is made vertically adjustable in its position in respect to the chimney.

Reference is made to the drawing, which forms a part of this specification, in which- Figure l is a sidesectional elevation of my improvement through the line 00 as. Fig. 2 is a plan view in section through the line y 52 Similar letters of reference indicate corresponding parts. v

A, the chimney; 'K, external casing surrounding the chimney. The space between chimney A and thell K forms the receptacle for the cinders or other solids that rise from the chimney. The cinders are removed from the receptacle through side doors J, made in casing K. B, a hollow annular conical'dcflecting cap or shell, placed directly over the center of the chimney. The top of the shell B is flat; its exterior sides are sloping; its interior is hollow, butprovided with parabolic deflecting-surfaces B that start from a common center, rise and curve in parabolic form upward, outward, and downward, as shown, to the lower edge of the shell. The central and upward sloping surfaces of the shell stand over the chimney, receive the impact of the products of combustion, and direct them outward. The downward-curved surfaces of the shell stand over the mouth of the annular receptacle between the chimney A and exterior casing K, and direct the solid matter down into said receptacle. The upper portion of the casing K is enlarged or made flaring, so that its interior diameter is equal to the largest diameter of the shell A. themouth of the casing K is provided with one or more thin annular inclined flanges, E, that project outward from the inner wall of the casin g Kinto the space between the chimney and the casing. One or more similar flanges, I, project in like manner from the exterior wall of the chimney. These flanges H I serve to retain the cinders and prevent the rise after they have fallen below the flanges within the receptacle. The deflecting cap or shellB is made vertically adjustable by means ofauy suitable height-regulating device, which, in this example, consists of the attachment to shell B at its center of a rod, E, the lower end of which connects with a crank on the rotary cross-rod D, which passes through both chimney and casing, and is provided with a hand wheel, F, locked in any desired. position by pin G outside of the casin g. 0 G O are guiderods attached to chimney A, upon which rods the cap B slides up or down, according to the direction in which the wheelF is turned. The height of the deflector B may be thus easily regulated to suit the character of the fuel and the nature of the cinders produced, and the draft of the chimney may be also varied.

In starting the fire the deflector may need, i

in some cases, to be raised to increase the chimney-draft.

The cinders arising from various kinds of fuel may be fine or coarse, requiring a special The inner edge of A regulation of the height of the deflector, ac the :top of the-chimney Avand the top of the cording to the fineness or 'coarsenessof-"the casing K are on thezsame level; that the dec'inders, to insure their arrest.
